BACKGROUND OF THE INVENTION

Serotonin (5-hydroxytryptamine, 5HT) mediates a wide variety of central and peripheral psychological and physiological effects through 14 mammalian 5HT receptor subtypes that are grouped into the 5HT₁-5HT₇ families (Sanders-Bush and Mayer, 2006). The 5HT₂ family consists of the 5HT_(2A), 5HT_(2B), and 5HT_(2C) membrane-bound G protein-coupled receptors (GPCRs) that signal primarily through Gα_(q) to activate phospholipase (PL) C and formation of inositol phosphates (IP) and diacylglycerol (DAG) second messengers (Raymond et al., 2001). The human 5HT_(2C) receptor (Saltzman et al., 1991) apparently is found exclusively in brain where it is widely expressed and putatively involved in several (patho)-physiological and psychological processes, including, ingestive behavior (Tecott et al., 1995), cocaine addiction (Fletcher et al., 2002; Rocha et al., 2002; Muller and Huston, 2006), sleep homeostasis (Frank et al., 2002), anxiety (Kennett et al., 1994; Sard et al., 2005; Heisler et al., 2007), depression (Tohda et al., 1989; Palvimaki et al., 1996), epilepsy (Heisler et al., 1998), Alzheimer's disease (Arjona et al., 2002; Stein et al., 2004), motor function (Heisler and Tecott, 2000; Segman et al., 2000), psychosis (Marquis et al., 2007; Siuciak et al., 2007) and response to antipsychotic drugs (Veenstra-VanderWeele et al., 2000; Reynolds et al., 2005). Thus, the importance of the 5HT_(2C) receptor as a pharmacotherapeutic target has been apparent for about 10 years, however, no 5HT_(2C)-specific drugs have been developed.

One challenge regarding drug discovery targeting the 5HT_(2C) receptor is that this GPCR shares a transmembrane domain (TMD) sequence identity of about 80% with the 5HT_(2A) receptor and about 70% with the 5HT_(2B) receptor (Julius et al., 1988; 1990). The highly conserved TMDs and similar second messenger coupling has made development of agonist ligands selective for the 5HT_(2C) receptor especially difficult. Nevertheless, there is compelling evidence that activation of 5HT_(2C) receptors reduces food intake and leads to anti-obesity effects. For example, 5-HT_(2C) knockout mice demonstrate increased feeding and obesity, and, they are resistant to the anorectic effects of d-fenfluramine (Tecott et al., 1995; Vickers et al., 1999; 2001; Heisler et al., 2002). Fenfluramine now is banned, because, although people using the drug showed weight loss due to activation of brain 5HT_(2C) receptors, fenfluramine also activates 5HT_(2A) receptors that may lead to adverse psychiatric (hallucinogenic) effects (Nichols, 2004) and 5HT_(2B) receptors which causes valvular heart disease (Connolly et al., 1997; Fitzgerald et al., 2000; Rothman et al., 2000; Roth, 2007) and pulmonary hypertension (Pouwels et al., 1990; Launay et al., 2002)—fatalities have resulted from the 5HT_(2B)-mediated effects.

Although an agonist ligand truly selective for 5HT_(2C) vs. 5HT_(2A) and/or 5HT_(2B) receptors has not been reported until this paper, it has been possible to partially elucidate the role of brain 5HT_(2C) receptors to attenuate cocaine use and dependence using very selective (i.e., at least 100-fold) 5HT_(2A) and 5HT_(2C) antagonists in rat cocaine self-administration paradigms. For example, the selective 5HT_(2A) antagonist M100907 (Kehne et al., 1996) does not alter responding rate for cocaine self-administration but the selective 5HT_(2C) antagonist SB242084 (Bromidge et al., 1997) increases the rate of cocaine self-administration dose-dependently (Fletcher et al., 2002). The tremendous potential of 5HT_(2C) agonist pharmacotherapy for psychostimulant addiction now is widely recognized (Bubar and Cunningham, 2006).

The pharmacotherapeutic relevance of the 5HT_(2C) receptor in obesity and neuropsychiatric disorders such as psychostimulant addiction has stimulated intense interest by pharmaceutical companies to develop a selective 5HT_(2C) agonist, however, all 5HT_(2C) agonists reported so far also activate 5HT_(2A) and/or 5HT_(2B) receptors (Nilsson, 2006). Nevertheless, the 5HT₂ agonist lorcaserin (APD356) recently went to Phase III clinical trials for obesity treatment even though it has only a modest 15-fold selectivity for activation of 5HT_(2C) receptors over 5HT_(2A) receptors (Jensen, 2006; Smith et al., 2006). Results reported here, however, are based on novel compounds synthesized in our laboratories, i.e., phenyl-3-dimethylamino-1,2,3,4-tetrahydronaphthalene (PAT) and cyclyl-3-dimethylamino-1,2,3,4-tetrahydronaphthalene (CAT) compounds, are full efficacy agonist at human 5HT_(2C) receptors, plus, it is an antagonist at 5HT_(2A) and 5HT_(2B) receptors.

G Protein-Coupled Receptors (GPCRs) can activate more than more type of G protein that results in multiple physiological/pharmacological effects, both pharmacotherapeutic and untoward side effects (Moniri et al., Journal of Pharmacology and Experimental Therapeutics, 311:274-281 (2004)). The phenomenon of multiple signaling pathways associated with a single GPCR can be described within the framework of the three-state model of GPCR activation, wherein, GPCRs isomerize between inactive and constitutively active states. GPCR activation causes dissociation of heterotrimeric (α,β,γ) G protein subunits—the Gα subunit can then activate transducer protein (e.g., PLC, AC) to alter second messenger concentration. It is now realized the same GPCR can couple to different Gα proteins to result in “multifunctional signaling”. A critical assumption of the GPCR multifunctional signaling theory is that a heterogeneity of active receptor conformations exists and that agonist ligands differ in their ability to induce, stabilize, or select among receptor conformations, as described in the “stimulus trafficking” hypothesis. It follows that, upon binding, agonist ligand chemical structural parameters are among the most important determinants of GPCR conformation that influences type of Gα protein and signaling pathway activated.

A survey of 105 articles on the activity of 380 antagonists on 73 biological G-protein-coupled receptor targets indicates that, in this sample dataset, 322 are inverse agonists and 58 (15%) are neutral antagonists. The predominance of inverse agonism agrees with theoretical predictions which indicate that neutral antagonists are the minority species in pharmacological space (Kenakin, Mol Pharmacol. (2004); 65:2-11).

The p90 ribosomal s6 kinases (RSKs) are a group of serine/threonine kinases that are constituents of the AGC subfamily in the human kinome (Nguyen, 2008). There are four RSK isoforms (RSK1-4) and each is a product of a separate gene. The RSK isoforms are characterized by 75%-80% sequence identity. Although the RSK isoforms are broadly distributed in human tissue, they exhibit variable tissue expression, which is an indication that they may be involved in different functions. The RSK isoforms are activated by extracellular signaling molecules that stimulate the Ras-ERK pathway. These molecules include a variety of different growth factors, cytokines, peptide hormones and neurotransmitters. It is noted that at this time, biological/pharmacological roles for each of the RSK isoforms is not established for most diseases, including, cancer.

RSKs phosphorylate a variety of proteins, including transcription factors, immediate-early gene products, translational regulators, enzymes, and structural proteins, that link RSKs as a family to many biological processes such as cell proliferation, cell differentiation, survival, and migration (Anjum and Blenis, 2008a).

RSK isoforms are overexpressed in 50% of human breast cancer tissue samples, indicating that regulation of RSK has been compromised—the link between RSK activity and tumor cell proliferation reveals RSKs as novel cancer drug targets (Gioeli et al., 1999; Smith et al., 2005).

There is compelling evidence for a link between RSKs and HIV infection. RSK2 was shown to have a reciprocal relationship with HIV-1 Tat. RSK2 is recruited and activated by HIV-1 Tat, and is itself also important to normal Tat function (Hetzer et al., 2005). Moreover, Kaposi sarcoma-associated herpesvirus interacts with RSKs and strongly stimulates their kinase activities (Kuang et al., 2009).

Structurally, the RSK isoforms are very similar (Nguyen, 2008). Each of the isoforms contains two functional catalytic domains that are separated by a large 100 amino acid linker region. The two kinase domains are distinct and contain nonidentical ATP-binding site. The NTKD is similar to p70 S6 kinase (p70 S6K1), and the CTKD is similar to the calcium/calmodulin protein kinases. Because of its molecular architecture, RSK offers two logical sites for inhibition: the ATP-binding site in the NTKD and the one in the CTKD. Site specific inhibitors for both ATP pockets have been identified.

Aberrant activation of the upstream activators of 90 kDa ribosomal S6 kinase (RSK) has been linked to many human diseases, including cancers. The RSK1 and RSK2 isoforms are amplified in breast and prostate tumours. The importance of RSK2 activation in haematopoietic transformation was recently shown in fibroblast growth factor receptor-3 (FGFR3)-expressing multiple myeloma cells. RSK3 was recently shown to function as a potential tumour suppressor in ovarian cancer. RSK4 was shown to participate in p53-dependent cell growth arrest, although aberrant expression of RSK4 has been observed in breast cancer. Mutations in the human RSK2 gene are associated with Coffin-Lowry syndrome (CLS), an X-linked disorder that is characterized by severe psychomotor retardation, digit and facial dysmorphisms, and progressive skeletal deformations. In fibroblasts from CLS patients, a drastic attenuation in induced Ser133 phosphorylation of the transcription factor CREB was detected in response to epidermal growth factor stimulation. Fibroblasts that were derived from patients with CLS have been useful in determining the function of RSK2 with respect to this human disease; however, differences found between these cells and RSK2-deficient mouse fibroblasts suggest that CLS might be a multivariable disease and mouse might not be the ideal system in which to study RSK2 function. Both the RSK2 and RSK4 genes are located on chromosome X, and recent data also implicate RSK4 in nonspecific X-linked mental retardation, but definitive evidence remains to be provided for RSK4 (Anjum and Blenis, 2008b).

DETAILED DESCRIPTION OF THE INVENTION

The present inventors have now discovered a therapeutic strategy that addresses selective disease treatment and prevention (i.e., having reduced or minimized adverse side effects) by selectively targeting 5-HT2c and/or RSK. Such interactions are relevant for modulation of 5-HT2c mediated disorders, particularly in certain neuropsychiatric disorder types where 5-HT2 mechanisms play a significant role.

Before further description of the present invention, and in order that the invention may be more readily understood, certain terms are first defined and collected here for convenience.

The term “administration” or “administering” includes routes of introducing the compound of the invention(s) to a subject to perform their intended function. Examples of routes of administration that may be used include injection (subcutaneous, intravenous, parenterally, intraperitoneally, intrathecal), oral, inhalation, rectal and transdermal. The pharmaceutical preparations may be given by forms suitable for each administration route. For example, these preparations are administered in tablets or capsule form, by injection, inhalation, eye lotion, ointment, suppository, etc. administration by injection, infusion or inhalation; topical by lotion or ointment; and rectal by suppositories. Oral administration is preferred. The injection can be bolus or can be continuous infusion. Depending on the route of administration, the compound of the invention can be coated with or disposed in a selected material to protect it from natural conditions which may detrimentally effect its ability to perform its intended function. The compound of the invention can be administered alone, or in conjunction with either another agent as described above or with a pharmaceutically-acceptable carrier, or both. The compound of the invention can be administered prior to the administration of the other agent, simultaneously with the agent, or after the administration of the agent.

TABLE 3 The compounds of the formulae herein include those wherein R₆ or R₈ are a substituent (e.g., alkyl, aryl, cycloalkyl) that is a moiety attached to the boron atom in a boronic acid compound delineated in Table 7.

Additional compounds of the invention include the following compounds of formula (V):

All enantiomers, diastereomers, racemates, racemic mixtures, enantioenriched mixtures, and diasteromeric mixtures of any of the compounds delineated above are contemplated by the invention.

From mutagenesis and modeling data, the PAT protonated (pH 7.4) amine forms an ionic bond with conserved 5HT2 residue D3.32 (Booth et al., 2009). Modeling results in Aim 3 also indicate the PAT amine orients close (˜2 Å) to S3.36 & Y7.43, thus, amine substituents (R1, Chart 1) with additional heteroatoms are proposed to form hydrogen bonds with these residues. Also, Aim 3 modeling results show the PAT N-alkyl moiety binds in a sterically-generous receptor space, thus, sterically large R1 heterocyclic substituents proposed may form van der Waals interactions with nearby 5HT2 residues. Para-substituted PAT analogs potently modulate amphetamine behaviors (Aim 4), thus, para-halogenated PATs are synthesized first, followed by meta-halogenated, pending in vivo results for previously synthesized meta-substituted PATs.

Meta-halogenated PATs demonstrated highest 5HT2 affinity and potent functional selectivity. Molecular modeling indicates the 5HT2 family binding pocket is sterically generous regarding interactions with substituents at the meta-position of the PAT pendant phenyl ring (Booth et al., 2009; Aim 3 results). Thus, various analogs were designed to facilitate additional hydrogen bonding and aromatic interactions with conserved 5HT2 residues W6.48 F6.51 F6.52 and Y7.43 that are hypothesized and known (mutagenesis data) to interact with the PAT (C4) pendant phenyl moiety.

Based on modeling studies (Booth, 2009; Aim 3), additional analogs were designed to form additional hydrogen bonds with conserved 5HT2 residues V3.33, S3.36, S5.43 & F6.52, hypothesized and known (mutagenesis data) to interact with the aromatic part of PAT tetrahydronaphthyl ring.

The invention also relates to the pharmaceutically acceptable salts and esters of the above-mentioned compounds.

Naturally occurring or synthetic isomers can be separated in several ways known in the art. Methods for separating a racemic mixture of two enantiomers include chromatography using a chiral stationary phase (see, e.g., “Chiral Liquid Chromatography,” W. J. Lough, Ed. Chapman and Hall, New York (1989)). Enantiomers can also be separated by classical resolution techniques. For example, formation of diastereomeric salts and fractional crystallization can be used to separate enantiomers. For the separation of enantiomers of carboxylic acids, the diastereomeric salts can be formed by addition of enantiomerically pure chiral bases such as brucine, quinine, ephedrine, strychnine, and the like. Alternatively, diastereomeric esters can be formed with enantiomerically pure chiral alcohols such as menthol, followed by separation of the diastereomeric esters and hydrolysis to yield the free, enantiomerically enriched carboxylic acid. For separation of the optical isomers of amino compounds, addition of chiral carboxylic or sulfonic acids, such as camphorsulfonic acid, tartaric acid, mandelic acid, or lactic acid can result in formation of the diastereomeric salts.

According to another embodiment, the invention provides compounds which associate with or bind to GPCR or binding pocket thereof produced or identified by the methods described herein.

Other pharmaceutically active compounds that may be used can be found in Harrison's Principles of Internal Medicine, Thirteenth Edition, Eds. T. R. Harrison et al. McGraw-Hill N.Y., N.Y.; and the Physicians Desk Reference 50th Edition 1997, Oradell N.J., Medical Economics Co., the complete contents of which are expressly incorporated herein by reference. The compound of the invention and the pharmaceutically active compound may be administered to, the subject in the same pharmaceutical composition or in different pharmaceutical compositions (at the same time or at different times).

In another aspect, the treatment method comprises that wherein the subject (e.g., patient) is identified as in need of such treatment. In another aspect, the treatment method comprises that wherein the subject (e.g., patient) is administered a compound or composition herein such that the subject is treated for a disease, disorder or symptom delineated herein.

Another object of the present invention is the use of a compound as described herein (e.g., of any formulae herein) in the manufacture of a medicament for use in the treatment of a RSK-mediated disorder. Another object of the present invention is the use of a compound as described herein (e.g., of any formulae herein) for use in the treatment of a RSK-mediated disorder.

Determination of a therapeutically effective amount or a prophylactically effective amount of the compound of the invention of the invention, can be readily made by the physician or veterinarian (the “attending clinician”), as one skilled in the art, by the use of known techniques and by observing results obtained under analogous circumstances. The dosages may be varied depending upon the requirements of the patient in the judgment of the attending clinician; the severity of the condition being treated and the particular compound being employed. In determining the therapeutically effective amount or dose, and the prophylactically effective amount or dose, a number of factors are considered by the attending clinician, including, but not limited to: the specific 5-HT2c and/or RSK disorder involved; pharmacodynamic characteristics of the particular agent and its mode and route of administration; the desired time course of treatment; the species of mammal; its size, age, and general health; the specific disease involved; the degree of or involvement or the severity of the disease; the response of the individual patient; the particular compound administered; the mode of administration; the bioavailability characteristics of the preparation administered; the dose regimen selected; the kind of concurrent treatment (i.e., the interaction of the compound of the invention with other co-administered therapeutics); and other relevant circumstances.

Treatment can be initiated with smaller dosages, which are less than the optimum dose of the compound. Thereafter, the dosage may be increased by small increments until the optimum effect under the circumstances is reached. For convenience, the total daily dosage may be divided and administered in portions during the day if desired. A therapeutically effective amount and a prophylactically effective amount of a compound of the invention of the invention is expected to vary from about 0.1 milligram per kilogram of body weight per day (mg/kg/day) to about 100 mg/kg/day.

Compounds determined to be effective for the prevention or treatment of 5-HT2c and/or RSK disorders in animals, e.g., dogs, chickens, and rodents, may also be useful in treatment of 5-HT2c and/or RSK disorders in humans. Those skilled in the art of treating 5-HT2c and/or RSK disease in humans will know, based upon the data obtained in animal studies, the dosage and route of administration of the compound to humans. In general, the dosage and route of administration in humans is expected to be similar to that in animals.

The identification of those patients who are in need of prophylactic treatment for 5-HT2C and/or RSK disorders is well within the ability and knowledge of one skilled in the art. Certain of the methods for identification of patients which are at risk of developing 5-HT2C and/or RSK disorders which can be treated by the subject method are appreciated in the medical arts, such as family history, and the presence of risk factors associated with the development of that disease state in the subject patient. A clinician skilled in the art can readily identify such candidate patients, by the use of, for example, clinical tests, physical examination and medical/family history.

A method of assessing the efficacy of a treatment in a subject includes determining the pre-treatment extent of a 5-HT2C and/or RSK disorder by methods well known in the art (e.g., determining level of markers for the 5-HT2C and/or RSK disorder) and then administering a therapeutically effective amount of a compound delineated herein according to the invention to the subject. After an appropriate period of time after the administration of the compound (e.g., 1 day, 1 week, 2 weeks, one month, six months), the extent of the 5-HT2C and/or RSK disorder is determined again. The modulation (e.g., decrease) of the extent or invasiveness of the 5-HT2C and/or RSK disorder indicates efficacy of the treatment. The extent or invasiveness of the 5-HT2C and/or RSK disorder may be determined periodically throughout treatment. For example, the extent or invasiveness of the 5-HT2C and/or RSK disorder may be checked every few hours, days or weeks to assess the further efficacy of the treatment. A decrease in extent or invasiveness of the 5-HT2C and/or RSK disorder indicates that the treatment is efficacious. The method described may be used to screen or select patients that may benefit from treatment with a modulating compound of a 5-HT2C and/or RSK disorder.

A method of assessing the efficacy of a treatment in a subject includes determining the pre-treatment extent of obesity (overweight) by methods well known in the art and then administering a therapeutically effective amount of a compound delineated herein alone or each in combination with an amphetamine compound according to the invention to the subject. After an appropriate period of time after the administration of the compound (e.g., 1 day, 1 week, 2 weeks, one month, six months), the extent of obesity (overweightness) is determined again. The modulation (e.g., decrease) of the extent of overweightness indicates efficacy of the treatment. The extent or invasiveness of obesity may be determined periodically throughout treatment. For example, the extent or invasiveness of overweightness may be checked every few hours, days or weeks to assess the further efficacy of the treatment. A decrease in extent or invasiveness of the overweightness indicates that the treatment is efficacious. The method described may be used to screen or select patients that may benefit from treatment with a modulating compound capable of activating selectively 5-HT2c (vs. 5-HT2a,b) receptors in combination with an amphetamine compound.

As used herein, “obtaining a biological sample from a subject,” includes obtaining a sample for use in the methods described herein. A biological sample is described above.

Yet another aspect presents a method to identify a compound that modulates the interaction of 5-HT2C and/or RSK or specific domains thereof. The method may include obtaining the crystal structure of 5-HT2C and/or RSK or specific domains thereof (optionally apo form or complexed) or obtaining the information relating to the crystal structure of 5-HT2C and/or RSK or specific domains thereof (optionally apo form or complexed), in the presence and/or absence of the test compound. Compounds may then be computer modeled into or on the 5-HT2C and/or RSK structure, or specific domains thereof (e.g., a binding site of the crystal structure) to predict stabilization of the interaction between the 5-HT2C and/or RSK or specific domains thereof and the test compound. Once potential modulating compounds are identified, the compounds may be screened using cellular assays, such as the ones identified herein and competition assays known in the art. Compounds identified in this manner are useful as therapeutic agents.

In another aspect, a compound of the invention is packaged in a therapeutically effective amount with a pharmaceutically acceptable carrier or diluent.

4. PHARMACEUTICAL COMPOSITIONS

The invention also provides a pharmaceutical composition, comprising an effective amount of a compound of the and a pharmaceutically acceptable carrier. In a further embodiment, the effective amount is effective to treat a 5-HT2C and/or RSK disorder, as described previously.

In an embodiment, the compound of the invention is administered to the subject using a pharmaceutically-acceptable formulation, e.g., a pharmaceutically-acceptable formulation that provides sustained delivery of the compound of the invention to a subject for at least 12 hours, 24 hours, 36 hours, 48 hours, one week, two weeks, three weeks, or four weeks after the pharmaceutically-acceptable formulation is administered to the subject.

In certain embodiments, these pharmaceutical compositions are suitable for topical or oral administration to a subject. In other embodiments, as described in detail below, the pharmaceutical compositions of the present invention may be specially formulated for administration in solid or liquid form, including those adapted for the following: (1) oral administration, for example, drenches (aqueous or non-aqueous solutions or suspensions), tablets, boluses, powders, granules, pastes; (2) parenteral administration, for example, by subcutaneous, intramuscular or intravenous injection as, for example, a sterile solution or suspension; (3) topical application, for example, as a cream, ointment or spray applied to the skin; (4) intravaginally or intrarectally, for example, as a pessary, cream or foam; or (5) aerosol, for example, as an aqueous aerosol, liposomal preparation or solid particles containing the compound.

The phrase “pharmaceutically acceptable” refers to those compound of the inventions of the present invention, compositions containing such compounds, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio.

The phrase “pharmaceutically-acceptable carrier” includes pharmaceutically-acceptable material, composition or vehicle, such as a liquid or solid filler, diluent, excipient, solvent or encapsulating material, involved in carrying or transporting the subject chemical from one organ, or portion of the body, to another organ, or portion of the body. Each carrier is “acceptable” in the sense of being compatible with the other ingredients of the formulation and not injurious to the patient. Some examples of materials which can serve as pharmaceutically-acceptable carriers include: (1) sugars, such as lactose, glucose and sucrose; (2) starches, such as corn starch and potato starch; (3) cellulose, and its derivatives, such as sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; (4) powdered tragacanth; (5) malt; (6) gelatin; (7) talc; (8) excipients, such as cocoa butter and suppository waxes; (9) oils, such as peanut oil, cottonseed oil, safflower oil, sesame oil, olive oil, corn oil and soybean oil; (10) glycols, such as propylene glycol; (11) polyols, such as glycerin, sorbitol, mannitol and polyethylene glycol; (12) esters, such as ethyl oleate and ethyl laurate; (l₃) agar; (14) buffering agents, such as magnesium hydroxide and aluminum hydroxide; (15) alginic acid; (16) pyrogen-free water; (17) isotonic saline; (18) Ringer's solution; (19) ethyl alcohol; (20) phosphate buffer solutions; and (21) other non-toxic compatible substances employed in pharmaceutical formulations.

Wetting agents, emulsifiers and lubricants, such as sodium lauryl sulfate and magnesium stearate, as well as coloring agents, release agents, coating agents, sweetening, flavoring and perfuming agents, preservatives and antioxidants can also be present in the compositions.

Examples of pharmaceutically-acceptable antioxidants include: (1) water soluble antioxidants, such as ascorbic acid, cysteine hydrochloride, sodium bisulfate, sodium metabisulfite, sodium sulfite and the like; (2) oil-soluble antioxidants, such as ascorbyl palmitate, butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), lecithin, propyl gallate, alpha-tocopherol, and the like; and (3) metal chelating agents, such as citric acid, ethylenediamine tetraacetic acid (EDTA), sorbitol, tartaric acid, phosphoric acid, and the like.

Compositions containing a compound of the invention(s) include those suitable for oral, nasal, topical (including buccal and sublingual), rectal, vaginal, aerosol and/or parenteral administration. The compositions may conveniently be presented in unit dosage form and may be prepared by any methods well known in the art of pharmacy. The amount of active ingredient which can be combined with a carrier material to produce a single dosage form will vary depending upon the host being treated, the particular mode of administration. The amount of active ingredient which can be combined with a carrier material to produce a single dosage form will generally be that amount of the compound which produces a therapeutic effect. Generally, out of one hundred percent, this amount will range from about 1 percent to about ninety-nine percent of active ingredient, preferably from about 5 percent to about 70 percent, more preferably from about 10 percent to about 30 percent.

Methods of preparing these compositions include the step of bringing into association a compound of the invention(s) with the carrier and, optionally, one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing into association a compound of the invention with liquid carriers, or finely divided solid carriers, or both, and then, if necessary, shaping the product.

Compositions of the invention suitable for oral administration may be in the form of capsules, cachets, pills, tablets, lozenges (using a flavored basis, usually sucrose and acacia or tragacanth), powders, granules, or as a solution or a suspension in an aqueous or non-aqueous liquid, or as an oil-in-water or water-in-oil liquid emulsion, or as an elixir or syrup, or as pastilles (using an inert base, such as gelatin and glycerin, or sucrose and acacia) and/or as mouth washes and the like, each containing a predetermined amount of a compound of the invention(s) as an active ingredient. A compound may also be administered as a bolus, electuary or paste.

In solid dosage forms of the invention for oral administration (capsules, tablets, pills, dragees, powders, granules and the like), the active ingredient is mixed with one or more pharmaceutically-acceptable carriers, such as sodium citrate or dicalcium phosphate, and/or any of the following: (1) fillers or extenders, such as starches, lactose, sucrose, glucose, mannitol, and/or silicic acid; (2) binders, such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinyl pyrrolidone, sucrose and/or acacia; (3) humectants, such as glycerol; (4) disintegrating agents, such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate; (5) solution retarding agents, such as paraffin; (6) absorption accelerators, such as quaternary ammonium compounds; (7) wetting agents, such as, for example, acetyl alcohol and glycerol monostearate; (8) absorbents, such as kaolin and bentonite clay; (9) lubricants, such a talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof; and (10) coloring agents. In the case of capsules, tablets and pills, the pharmaceutical compositions may also comprise buffering agents. Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugars, as well as high molecular weight polyethylene glycols and the like.

A tablet may be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared using binder (for example, gelatin or hydroxypropylmethyl cellulose), lubricant, inert diluent, preservative, disintegrant (for example, sodium starch glycolate or cross-linked sodium carboxymethyl cellulose), surface-active or dispersing agent. Molded tablets may be made by molding in a suitable machine a mixture of the powdered active ingredient moistened with an inert liquid diluent.

The tablets, and other solid dosage forms of the pharmaceutical compositions of the present invention, such as dragees, capsules, pills and granules, may optionally be scored or prepared with coatings and shells, such as enteric coatings and other coatings well known in the pharmaceutical-formulating art. They may also be formulated so as to provide slow or controlled release of the active ingredient therein using, for example, hydroxypropylmethyl cellulose in varying proportions to provide the desired release profile, other polymer matrices, liposomes and/or microspheres. They may be sterilized by, for example, filtration through a bacteria-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved in sterile water, or some other sterile injectable medium immediately before use. These compositions may also optionally contain opacifying agents and may be of a composition that they release the active ingredient(s) only, or preferentially, in a certain portion of the gastrointestinal tract, optionally, in a delayed manner. Examples of embedding compositions which can be used include polymeric substances and waxes. The active ingredient can also be in micro-encapsulated form, if appropriate, with one or more of the above-described excipients.

Liquid dosage forms for oral administration of the compound of the invention(s) include pharmaceutically-acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active ingredient, the liquid dosage forms may contain inert diluents commonly used in the art, such as, for example, water or other solvents, solubilizing agents and emulsifiers, such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor and sesame oils), glycerol, tetrahydrofuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof.

In addition to inert diluents, the oral compositions can include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, coloring, perfuming and preservative agents.

Suspensions, in addition to the active compound of the invention(s) may contain suspending agents as, for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth, and mixtures thereof.

Pharmaceutical compositions of the invention for rectal or vaginal administration may be presented as a suppository, which may be prepared by mixing one or more compound of the invention(s) with one or more suitable nonirritating excipients or carriers comprising, for example, cocoa butter, polyethylene glycol, a suppository wax or a salicylate, and which is solid at room temperature, but liquid at body temperature and, therefore, will melt in the rectum or vaginal cavity and release the active agent.

Compositions of the present invention which are suitable for vaginal administration also include pessaries, tampons, creams, gels, pastes, foams or spray formulations containing such carriers as are known in the art to be appropriate.

Dosage forms for the topical or transdermal administration of a compound of the invention(s) include powders, sprays, ointments, pastes, creams, lotions, gels, solutions, patches and inhalants. The active compound of the invention(s) may be mixed under sterile conditions with a pharmaceutically-acceptable carrier, and with any preservatives, buffers, or propellants which may be required.

The ointments, pastes, creams and gels may contain, in addition to compound of the invention(s) of the present invention, excipients, such as animal and vegetable fats, oils, waxes, paraffins, starch, tragacanth, cellulose derivatives, polyethylene glycols, silicones, bentonites, silicic acid, talc and zinc oxide, or mixtures thereof.

Powders and sprays can contain, in addition to a compound of the invention(s), excipients such as lactose, talc, silicic acid, aluminum hydroxide, calcium silicates and polyamide powder, or mixtures of these substances. Sprays can additionally contain customary propellants, such as chlorofluorohydrocarbons and volatile unsubstituted hydrocarbons, such as butane and propane.

The compound of the invention(s) can be alternatively administered by aerosol. This is accomplished by preparing an aqueous aerosol, liposomal preparation or solid particles containing the compound. A nonaqueous (e.g., fluorocarbon propellant) suspension could be used. Sonic nebulizers are preferred because they minimize exposing the agent to shear, which can result in degradation of the compound.

Ordinarily, an aqueous aerosol is made by formulating an aqueous solution or suspension of the agent together with conventional pharmaceutically-acceptable carriers and stabilizers. The carriers and stabilizers vary with the requirements of the particular compound, but typically include nonionic surfactants (Tweens, Pluronics, or polyethylene glycol), innocuous proteins like serum albumin, sorbitan esters, oleic acid, lecithin, amino acids such as glycine, buffers, salts, sugars or sugar alcohols. Aerosols generally are prepared from isotonic solutions.

Transdermal patches have the added advantage of providing controlled delivery of a compound of the invention(s) to the body. Such dosage forms can be made by dissolving or dispersing the agent in the proper medium. Absorption enhancers can also be used to increase the flux of the active ingredient across the skin. The rate of such flux can be controlled by either providing a rate controlling membrane or dispersing the active ingredient in a polymer matrix or gel.

Ophthalmic formulations, eye ointments, powders, solutions and the like, are also contemplated as being within the scope of the invention.

Pharmaceutical compositions of the invention suitable for parenteral administration comprise one or more compound of the invention(s) in combination with one or more pharmaceutically-acceptable sterile isotonic aqueous or nonaqueous solutions, dispersions, suspensions or emulsions, or sterile powders which may be reconstituted into sterile injectable solutions or dispersions just prior to use, which may contain antioxidants, buffers, bacteriostats, solutes which render the formulation isotonic with the blood of the intended recipient or suspending or thickening agents.

Examples of suitable aqueous and nonaqueous carriers, which may be employed in the pharmaceutical compositions of the invention include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol, and the like), and suitable mixtures thereof, vegetable oils, such as olive oil, and injectable organic esters, such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of coating materials, such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants.

These compositions may also contain adjuvants such as preservatives, wetting agents, emulsifying agents and dispersing agents. Prevention of the action of microorganisms may be ensured by the inclusion of various antibacterial and antifungal agents, for example, paraben, chlorobutanol, phenol sorbic acid, and the like. It may also be desirable to include isotonic agents, such as sugars, sodium chloride, and the like into the compositions. In addition, prolonged absorption of the injectable pharmaceutical form may be brought about by the inclusion of agents which delay absorption such as aluminum monostearate and gelatin.

In some cases, in order to prolong the effect of a drug, it is desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material having poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally-administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle.

Injectable depot forms are made by forming microencapsule matrices of compound of the invention(s) in biodegradable polymers such as polylactide-polyglycolide. Depending on the ratio of drug to polymer, and the nature of the particular polymer employed, the rate of drug release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions which are compatible with body tissue.

When the compound of the invention(s) are administered as pharmaceuticals, to humans and animals, they can be given per se or as a pharmaceutical composition containing, for example, 0.1 to 99.5% (more preferably, 0.5 to 90%) of active ingredient in combination with a pharmaceutically-acceptable carrier.

Regardless of the route of administration selected, the compound of the invention(s), which may be used in a suitable hydrated form, and/or the pharmaceutical compositions of the present invention, are formulated into pharmaceutically-acceptable dosage forms by conventional methods known to those of skill in the art.

Actual dosage levels and time course of administration of the active ingredients in the pharmaceutical compositions of the invention may be varied so as to obtain an amount of the active ingredient which is effective to achieve the desired therapeutic response for a particular patient, composition, and mode of administration, without being toxic to the patient. An exemplary dose range is from 0.1 to 10 mg per day.

A preferred dose of the compound of the invention for the present invention is the maximum that a patient can tolerate and not develop serious side effects. Preferably, the compound of the invention of the present invention is administered at a concentration of about 0.001 mg to about 100 mg per kilogram of body weight, about 0.001-about 10 mg/kg or about 0.001 mg-about 100 mg/kg of body weight. Ranges intermediate to the above-recited values are also intended to be part of the invention.

Synthetic Schemes

The compounds of the invention can be made according to the following synthetic schemes.

Scheme A: Synthesis of N-substituted PATs in Chart 1. Reaction of styrene or halostyrene 7 with [2] provides the 4-substituted-tetralen-2-ol phenyl acetate 8. Reduction of 8 gives tetral-2-ol 9. Trans-(2S,4R)—N-substituted PATs 10 are prepared by tosylation of 9, followed by S_(N)2 inversion with cyclic amines (pyrrolidine, piperidine, etc) and enantiomer separation by chiral stationary phase (CSP)-HPLC (Vincek & Booth 2009).

Scheme B: Alternative approach. Aldol condensation of phenyl acetone 11 with benzaldehyde or halobenzaldehydes 12 in presence of KOH affords enone derivatives 13. Tetralone intermediates 14 are obtained from treatment of 13 with polyphosphoric acid as we reported previously (Bucholtz 1999). Trans-(2S,4R)-PATs 10 are prepared from reductive amination of 14 (Abdel-Magid 1996), followed by CSP-HPLC.

Scheme C: Synthesis of meta-substituted PATs in Chart 2. We published (Vincek & Booth, 2009), several novel approaches to obtain meta-substituted-phenyl PATs. Readily available reagents 1 and [2] yield versatile 3-substituted-phenyltetralen-2-ol phenylacetates 3. The 3-substituted aryl and enol phenylacetate functionalities on 3 make these molecules useful for asymmetric transformations and diversified organic syntheses. In 3-steps, (a) asymmetric transfer hydrogenation, (b) tosylation, and (c) S_(N)2 inversion with dimethylamine, enantio-enriched cis-(2R,4R)-4, cis-(2R-4R)-5; trans-(2R-4S) and (2S,4R) products are obtained by CSP-HPLC.

Scheme D: Alternative approach. Suzuki coupling of 4-(3-bromophenyl)-tetralen-2-ol phenylacetate 3a (i.e., 3 in Scheme 1 where R¹=Br) with substituted-boronic acid in reaction (d) provides 4-(3-substituted-phenyl)-tetralen-2-ol phenylacetates 6 (Vincek & Booth, 2009). Many boronic acid Suzuki coupling reagents are available (Chemfiles, 2007).

Scheme E: Synthesis of PAT with tetrahydronapthyl substituents in Chart 3. Readily prepared 1 and commercially available 2 yield substituted phenyltetralen-2-ol phenylacetates 3 using trifluoro-acetic anhydride (TFAA) (Vincek & Booth, 2009). Compound 3 is reduced by sodium borohydride to afford racemic cis-ol 4 that is directly tosylated and converted to the trans-dimethylamine 5. CSP-HPLC is used to separate (+)-trans-(2R,4S)- and (−)-trans-(2S,4R)-5. These new PAT analogs could be reduced by boron tribromide to afford another series of new compounds 6. Conversion of 4 to 7 by the Mitsunobu reaction, followed by tosylation, amination and CSP-HPLC enantiomeric separation gives (+)- and (−)-cis-PATs 8 & 9.

Scheme F: Alternative approach: We have previously used Scheme 6 (Bucholtz et al., 1999; Booth et al., 2009) wherein separation of racemic-cis and racemic-trans isomers by column chromatography is followed by diastereomeric recrystallization or CSP-HPLC to obtain single-enantiomer PAT analogs.

EXAMPLES

The invention is further illustrated by the following examples which are intended to illustrate but not limit the scope of the invention.

Example 1 Chemicals

All reagents were obtained from commercial suppliers and used without further purification. ¹H and ¹³C NMR were collected at resonance frequencies 400 and 100 MHz correspondingly, in CDCl₃. The chemical shifts are reported in ppm from tetramethylsilane. Flash column chromatography was conducted using silica gel 60 (230-400 mesh). Melting points were determined on a MeI-Temp apparatus equipt with a mercury thermometer. HPLC chiral separations were determined by an HPLC instrument equipped with a RegisCell™ (5 μm, 25 cm×10 mm i.d.) column. Minor peaks (<5%) in some ¹H & ¹³C NMR spectra were attributed to the formation of a regioisomer.

[³H]-Ketanserin (specific activity 72.2 Ci/mmol) and myo-[2-³H(N)]-Inositol (specific activity 18.5 Ci/mmol) were purchased from Perkin-Elmer Life Science (Boston, Mass.) and [N⁶-methyl-³H]-mesulergine (specific activity 72.0 Ci/mmol) from Amersham Biosciences (GE healthcare, Piscataway, N.J.). Other compounds were obtained in highest purity from Sigma-Aldrich (St. Louis, Mo.).

Clonal Cell Culture and Transfection

All cell lines are maintained by following ATCC suggestion, Chinese Hamster Ovary cells (CHO-K1, ATCC CCL-61) in Ham's F-12 medium supplemented with 10% fetal bovine serum, 1% sodium bicarbonate (Mediatech 25-035-CI), 10 IU/ml Penicillin and 10 ug/ml Streptomycin, and human embryonic kidney (HEK) 293 in minimum essential medium (Eagle) (MEM) with 2 mM L-glutamine adjusted to contain 1.5 g/L sodium bicarbonate, 0.1 mM non-essential amino acids, and 1.0 mM sodium pyruvate (90%) with 10% fetal bovine serum, 10 IU/ml Penicillin and 10 ug/ml Streptomycin. Cells are grown at 37° C. in a humidified incubator with 5% CO₂. The cDNAs encoding the human 5-HT_(2A), 5-HT_(2B), and 5-HT_(2C) receptors (wild type) are purchased from UMR (Rolla, Mo.) for transient transfection of the clonal cells. For radioreceptor binding assays, 5-HT_(2A), 5-HT_(2B), and 5-HT_(2C) receptor membranes are prepared from transfected CHO-K1 cells. For functional assays measuring activity of PLC/IP formation, transfected CHO-K1 cells are used for 5-HT_(2A) and 5-HT_(2C) receptors. For 5HT_(2B) receptors, however, more robust and consistent results for the PLC/IP assay are obtained using transfected HEK cells (Setola et al., 2005). Twenty-four hours before transfection, cells are seeded at 40% confluence in 100 mm dishes for radioreceptor binding assays or at 10⁵ cells per well in 12-well plates for functional assays. CHO-K1 cells are transiently transfected with 12 μg of plasmid and 32 μl of lipofectamine (Invitrogen) per 100 mm dish for radioreceptor binding assays, or, 0.8 μg plasmid and 4.0 μl of lipofectamine per well for functional assays. For 5-HT_(2B) functional assays using HEK cells, 24 μg plasmid DNA is mixed with 60 μl of Lipofectamine 2000 (Invitrogen) to transfect 1-2×10⁶ cells in a 10-cm plate. Cells are allowed to express transfected receptors for another 24 hrs (Herrick, 1997).

Radio Receptor Assays

Radioreceptor saturation and competition binding assays are performed using membrane homogenates, similar to our methods reported previously for the phylogenetically closely related histamine H₁ GPCR (Booth, 2002; Moniri et al., 2004). [³H]-Ketanserin is used to radiolabel 5-HT_(2A) receptors and [³H]-mesulergine for 5-HT_(2B) and 5-HT_(2C) receptors. Briefly, forty-eight hours following CHO cell transfection, cells are harvested and homogenized in 50 mM Tris-HCl containing 0.1% ascorbic acid and 4.0 mM CaCl₂ at pH 7.4 (assay buffer). The homogenate is centrifuged at 35,000 g for 25 min and the resulting membrane pellet is re-suspended in assay buffer. Protein concentration is determined by the method of Lowry et al. (Lowry, 1951). For saturation binding assays, membrane suspension containing 100 μg protein is incubated with 0.1-5.0 nM [³H]-ketanserin (5-HT_(2A) receptors) or 0.1-20 nM [³H]-mesulergine (5-HT_(2B) and 5-HT_(2C) receptors) in a total assay buffer volume of 250 μA Non-specific binding is determined in the presence of 10 μM methysergide (5-HT_(2A) receptors) or 1.0 μM mianserin (5-HT_(2B) and 5-HT_(2C) receptors). Competition binding assays are conducted similarly with 1.0 nM [³H]-ketanserin or [³H]-mesulergine. Incubation of radioreceptor binding assay mixtures is for 1.0 h at 37° C., with termination by rapid filtration through Whatman GF/B filters using a 96-well cell harvester (Tomtec, Hamden, Conn.). The membrane-bound [³H]-radioligand retained on the filter discs is quantified by liquid scintillation spectrometry. Data are analyzed by nonlinear regression using the sigmoidal curve-fitting algorithms in Prism 4.03 (GraphPad Software Inc., San Diego, Calif.). Ligand affinity is expressed as an approximation of K_(i) values by conversion of the IC₅₀ data to K_(0.5) values using the equation K_(0.5)=IC₅₀/1+L/K_(D), where L is the concentration of radioligand having affinity K_(D) (Cheng, 1973).

Assay for Activation of PLC and [³H]-IP Formation

Functional activation of PLC is measured as [³H]-IP formation in CHO cells transiently expressing serotonin 5-HT_(2C) receptors or HEK cells transiently expressing serotonin 5-HT_(2A) or 5-HT_(2B) receptors, as previously reported (Moniri et al., 2004). Briefly, thirty-two hours following transfection, cells in inositol-free Dulbecco's modified Eagle's medium (DMEM) are incubated for twelve hours with 1.0 μCi/ml myo-[2-³H]-inositol, the radiolabeled precursor of the PLC-β substrate phosphatidylinositol. Cells then are washed and incubated in DMEM containing 10 mM lithium chloride, 10 μM pargyline (with addition of 5% dialyzed fetal bovine serum for HEK cells), and, various concentrations of test ligand for 45-60 min at 37° C. After aspiration of media, wells are lysed by incubation with 50 mM formic acid (15-60 min). Formic acid is neutralized with ammonium hydroxide and contents from each well are added to individual AG1-X8 200-400 formate resin anion exchange columns. Ammonium formate/formic acid (1.2 M/0.1 M) is used to elute [³H]-IP directly into scintillation vials for counting of tritium by liquid scintillation spectrometry. Resulting data are analyzed using the nonlinear regression algorithms in Prism 4.03 and are expressed as mean percentage of control [³H]-IP formation, with potency expressed as concentration required to stimulate (EC₅₀) or inhibit (IC₅₀) maximal basal (constitutive) [³H]-IP formation by 50%±S.E.M.

Functional activation of PLC is measured as [³H]-IP formation in CHO cells transiently expressing 5-HT_(2A) or 5-HT_(2C) receptors and HEK cells transiently expressing 5HT_(2B) receptors, as previously reported by our lab (Booth, 2002; Moniri et al., 2004). Briefly, thirty-two hours following transfection, cells in inositol-free Dulbecco's modified Eagle's medium (DMEM) are labeled with 1 μCi/ml myo-[2-³H]-inositol, a precursor of the PLC-13 substrate phosphatidylinositol. Cells then are washed and incubated in DMEM containing 25 mM Hepes (pH 7.4), 10 mM LiCl, 10 μM pargyline (with addition of 5% dialyzed FBS for HEK cells), and various concentrations of test ligand for 45-60 min at 37° C. After aspiration of media, wells are placed on ice and lysed by incubation with 50 mM formic acid (15-60 min). Formic acid is neutralized with ammonium hydroxide and all contents from each well are added to individual AG1-X8 200-400 formate resin anion exchange columns. Ammonium formate/formic acid (1.2 M/0.1 M) is used to elute [³H]-IP directly into scintillation vials for counting of tritium by liquid scintillation spectrometry. Resulting data are analyzed using the nonlinear regression algorithms in Prism 4.03 and are expressed as mean percentage of control [³H]-IP formation, with potency expressed as concentration required to produce 50% maximal [³H]-IP formation (EC₅₀)±S.E.M (n≧3).

Example 2

Radioligand saturation binding analysis of 5HT-subtype receptors: There is no measurable specific radioligand binding using membranes prepared from null-transfected CHO and HEK cells. Using membranes prepared from CHO cells transiently transfected with 5-HT_(2A), 5-HT_(2B), or 5-HT_(2C) cDNA, however, saturable specific radioligand binding occurs. [³H]-Ketanserin binds to an apparent single population of 5HT_(2A) receptors (B_(max)=1.73±0.11 μmol/mg protein) with high affinity (K_(D)=0.80±0.03 nM). Similarly, [³H]-mesulergine labels a single population of 5HT_(2B) receptors with B_(max)=1.13±0.39 μmol/mg protein and K_(D)=5.19±0.36 nM. [³H]-mesulergine also labels an apparent single population of 5HT_(2C) receptors (B_(max)=8.37±0.15 μmol/mg prot) with high affinity (K_(D)=0.88±0.03 nM).

Kinase inhibition activity of RSKs and other kinases are known in the art. Assays for RSK activity are performed essentially as described in Jeffrey A. Smith, Celeste E. Poteet-Smith, Yarning Xu, Timothy M. Errington, Sidney M. Hecht, and Deborah A. Lannigan Cancer Res 2005; 65: (3), pp. 1027-1034. Feb. 1, 2005.

Example 4 Synthesis of Meta-Substituted Compounds and Separation of Enantiomers

General synthetic methods: Relevant methodologies useful; in synthesizing compounds of the invention are known in the art and described in our synthetic medicinal chemistry publications (including e.g., Ghoneim, O. M.; Legere, J. A.; Golbraikh, A.; Tropsha, A.; Booth, R. G. Bioorg. Med. Chem. 2006, 14, 6640; Bucholtz, E. C.; Brown, R. L.; Tropsha, A.; Booth, R. G.; Wyrick, S. D. J. Med. Chem. 1999, 42, 3041; Wyrick S D, Booth R G, Myers A M, Owens C E, Kula N S, Baldessarini R J, McPhail A T, and Mailman R B (1993) Synthesis and pharmacological evaluation of 1-phenyl-3-amino-1,2,3,4-tetrahydronaphthalenes as ligands for a novel receptor with sigma-like neuromodulatory activity. J Med Chem 36:2542-2551). In vitro pharmacological studies initially will use racemic cis and trans products. Racemic compounds can be resolved to (+)- and (−)-enantiomers by derivatization to the diastereomeric salt followed by differential crystallization or synthesized de novo using a chiral reduction step. Absolute configuration is assigned by single crystal X-ray crystallography or spectrophotometric methods (NMR, optical rotation) by comparison to pure enantiomers already synthesized. Products (as HCl salts) characterized for purity using NMR, elemental analysis, mass spectrometry, melting point and thin layer chromatography.

Scheme 1: Meta-substituted compounds: Methods were modified from methodologies cited above and others known in the art. The Claisen-Schmidt reaction using meta-substituted aldehyde 2 gave the α,β-unsaturated ketone 3, which was cyclized to the ketone 4 and reduced using NaBH₄. The (±)-cis and (±)-trans free base 7 was converted to the (1R)-(−)- or (1S)-(+)-camphor-10-sulfonic acid diastereomeric salt, which underwent differential recrystallization to afford (+)- or (−)-enantiomer, that was alkylated to product 8.

Scheme 2: Use of chiral reducing agent to obtain PAT analog stereoisomers: Di-isopinocamphenyl-borane (DIP) analogs recently were reported as stereoselective reducing agents for ketones with structures similar to the ketone 4 in Scheme 2 (see, e.g., Cha et al., 2005).

Synthesis of New PAT Analogs with Changes to the C(1) Pendant Phenyl Substituent

It was indicated based on binding, function, 3D QSAR, and molecular modeling results, that the (−)-trans-substituted phenyl aminotetralin (PAT) C(1) pendant phenyl moiety is critical to providing full-efficacy 5HT_(2C) agonist activity without activation of 5HT_(2A) and 5HT_(2B) receptors.

Scheme 3 In Step A, β-tetralone (1) was refluxed with benzene ruthenium (II) chloride dimer and the chiral ligand (R,R)—N-(2-amino-1,2-diphenylethyl)-p-toluenesulfonamide ((R,R)—NAPTS) to give the (R)-β-tetralol (2) (Mogi et al., 2004). In Step B, the (R)-β-tetralol (2) was converted to the tert-butyldimethylsilyl (TBDMS) derivative (3) (TBDMS protecting group to prevent bromination at adjacent benzylic position). In Step C, the TBDMS protected compound was brominated with N-Bromosuccinimide (Agarwal et al., 1990) under reflux in anhydrous CCl₄ to give the brominated common intermediate (4), separated to cis and trans bromo compounds by flash column chromatography. In Step D, each (cis and trans) brominated intermediate (4) was reacted with commercially available boronic acids (R₂B(OH)₂, R₂=an alkyl, alkenyl, or aryl group; see for example the groups exemplified in Table 7 boronic acid compounds) under a Nickel-Catalyzed Suzuki reaction (Gonzalez-Bobes et al) using NiI₂/trans-2-aminocyclohexanol with sodium bis(trimethylsilyl)amide under reflux to make the various cis and trans PAT analogs. In Step E, the TBDMS protected PAT analogs were deprotected using tetrabutylammonium fluoride (TBAF) in tetrahydrofuran. In Step F, the cis and trans hydroxyl PAT analogs were converted in one-pot to the corresponding trans and cis azido PAT intermediates (7) using a Mitsunobu reaction with zinc azide/bis-pyridine complex, diisopropyl azodicarboxylate (DIAD) and triphenylphosphene (Vorogushin et al., 2003). In Step G, the azido PAT derivatives were reduced to the corresponding PAT amines (8). In Step H, these enantiomeric cis and trans amines were converted to the dimethylated PAT analogs (9) using Eschweiler-Clarke methylation with formic acid/formaldehyde under reflux.

Compounds were resolved to (+)- and (−)-enantiomers by derivatization of the un-methylated free amine to the diastereomeric salt followed by differential crystallization or synthesized de novo using a chiral reduction step. Absolute configuration was assigned by single crystal X-ray crystallography or spectrophotometric methods (NMR, optical rotation) by comparison to pure enantiomers already synthesized. Products (as HCl salts) were characterized for purity using NMR, elemental analysis, mass spectrometry, melting point and thin layer chromatography. Compounds specifically delineated herein include those wherein R₂ is a chemical group or moiety (e.g, substituted or unsubstituted alkyl, alkenyl, or aryl group) attached to the boron atom in the boronic acid compounds of Table 7. Additional procedures for preparation of compounds herein are also described in PCT International Publication No. WO 2008/156707 (application no. PCT/US2008/007458).

Synthesis of Analogs

Trifluoroacetyl mixed anhydride and 3-halostyrenes (fluoro, chloro, and bromo) underwent cascade Friedel-Crafts cycli-acylalkylation, enolization, and O-acylation for 4-(3-halophenyl)-3,4-dihydronaphthalen-2-yl phenylacetates (bromo, 50%), without additional solvent. Base alcoholysis of masked 4-phenyltetral-2-one revealed the keto group for in situ asymmetric transfer hydrogenation. The bromo-derivative underwent Suzuki coupling with phenylboronic acid for 4-(biphen-3-yl)-3,4-dihydronaphthalen-2-yl phenylacetate, and provided a short efficient route to trans-4-phenyl-2-aminotetralins.

Cascade FC-CAA, enolization, and O-acylation was investigated with TFAA activated phenylacetic acid, styrene or 3-halostyrenes. Mild heating of reactive styrene 12a with [9] accelerated the inherently slow enolization (see, a) Nevy, J. B.; Hawkinson, D. C.; Blotny, G.; Yao, X.; Pollack, R. M. J. Am. Chem. Soc. 1997, 119, 12722. b) Yao, X.; Gold, M. A.; Pollack, R. M. J. Am. Chem. Soc. 1999, 121, 6220) of 3a to provide 4a (15%). In the absence of heating, complex mixtures resulted in loss of reactive 3a. Moderately reactive 3-halostyrenes with equimolar or up to 3-equiv of [9] provided halogenated 3 and 4. Fluorostyrene 12b with equimolar [9] gave major 3b (42%) and minor 4b (8%). Chlorostyrene 12c with 3-equiv of [9] gave 3c (70%). Further treatment of 3c with equimolar [9] gave 4c (38%). Warming to rt over 24 h bromostyrene 12c with 3-equiv of [9] gave 4d (50%), a 3-fold increase in yield from non-halogenated 4a.
